To quote an unknown graffiti artist, "Time doesn't exist, only clocks exist". In my opinion, there is no entity of time. According to the philosophy of presentism, the past and future are imagined concepts while only the present moment is real. Simply put, everything that has happened in the "past" ceased to exist after it ended, every single moment no longer exists once it's over, and similarly the future is imaginary because time cannot exist before and after it has happened. Now, many people claim that time exists simply because of seconds and minutes and hours and days, but those are just measurements. What are the clocks actually counting? Time is simply a social concept used in order to count until a certain thing happens, or to plan for something to happen.
Time does exist, because it has been created by society. Proof of past and present is as follows. Individuals that are older than others are able to tell stories and recount memories of the past, and have them coincide with accounts from others through personal experiences, photographs etc. Time is essentially a way to logically reference points of occurrence. Con's main argument against the existence of time fails because it bases the existence of time off of the present existence of things that occurred in the past, which by laws of physics is impossible. The existence of time in itself is independent of things that occur in the past or present, therefore, saying that time cannot exist because everything in the past does not exist in the present is shortsighted.
My argument is that time itself doesn't exist, but the measurement of time does. What I'm trying to state is that even though society has created "time" as a measurement, that doesn't mean that what they are measuring is real. A clock can count down until a spaceship launches, but the clock isn't exactly counting anything; nothing is happening, there is nothing to count, the clock is simply displaying numbers in a systematic fashion, and these numbers have no purpose but to specify that when the clock gets to one, the spaceship will launch. What had been created in the past may still exist in the present moment, but that is not evidence that there is some fourth-dimensional thing happening. Some people even believe that the past didn't actually exist, that we simply think it did, that we only live in the present moment and, to quote a movie in order to get the point across, 'The past is just a story we tell ourselves'.
